The CHIANTI database has the following primary ASCII files for this ion:
contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.
Theoretical energies:
Del Zanna, G., Storey, P.J., Badnell, N.R., Mason, H. E., 2012, A&A, 541, A90
Note: the theoretical energies are the 'best energies', i.e.
are the empirically-adjusted theoretical energies.
Experimental energies:
Del Zanna, G., Berrington, K. A., & Mason, H. E. 2004, A&A, 422, 731

contains wavelengths, gf and A values of the transitions. The wavelengths are based on the experimental energy levels and should be the best available. Wavelengths calculated from the theoretical energies are of an indeterminate accuracy and their values are presented as negative values of the calculated wavelength.

contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).
Produced for the CHIANTI database v.8 by Giulio Del Zanna Mar 2013 Only excitations form the lowest 24 levels are included. Del Zanna, G., Storey, P.J., Badnell, N.R., Mason, H. E., 2012, A&A, 541, A90 Data from
contains the spline fits to the scaled proton collision strengths.
%filename: fe_10.psplups
%rates: Bhatia A.K., Doschek, G.A., ADNDT 60, 97, 1995
%rates: Bely O., Faucher P., A&A 6, 88, 1970 (for 1-2 transition)
%energies: Observed energies from .elvlc file, except for level 10 for which
the theoretical energy from the .elvlc file is used.
%comment: For all transitions except 1 - 2, the rates were only tabulated at
one temperature. I have fit this data with a straight line that is
forced to be zero at a scaled temperature of 0 to emulate the
behaviour of proton rates.
%comment: Fitted using single_temp.pro with scalx=0.90
